Well I can cry, but not very often maybe two or three times a year. And that's often because of my anger, rarely because of sadness. I almost have the same problem with anger though, Of course I feel anger. But it's like it just burn within me, without getting out. so all people say that i'm the type that never cries and never gets angry. but that's just because I don't let it out, but the problem is that I don't know how to let it out or express it. And it always left me extremly tired and sad afterwards. I hope you understand what I mean, it's a little hard to explain.
